METAL-FORMING TOOL.

SPECIFICATION forming part of Letters Patent No. 410,606, datedSeptember 10, 1889.

Application filed June 16, 1888. Serial No. 277,398. (No model.)

To all whont it may concern.-

Be it known that I, ALEXANDER S. PATTON, a citizen of the United States,residing at Creighton, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements in Toolsfor Rounding Off Square or other Irregular- Shaped Irons or other Metalsand I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification.

My invention relates to a tool for forming into a round shape pieces ofiron or other metals.

In the accompanying drawings, Figure 1 is a full side view of my device,and Fig. 2 is a full side view of another form of such tool.

A A are jaws fixed to handles I) b by bolt or rivet at b B B arecorrugated dies, and are movable.

b b are corrugations on the concave sides of the dies B B.

In Fig. 2 I show a modification of my invention, wherein B B are thejaws; b, the corrugations; I) I), the handles joined or pivoted at 12The difference between the two tools is mainly in this, that in the toolshown in Fig. 2 there are no adjustable corrugated dies such as I showin Fig. 1. I expect that, as a rule, the trade will prefer the toolshown in Fig. 1, for the reason that it is constructed so as to receivenew dies or different-sized dies, to be removed and changed at will,while in the tool shown in Fig. 2 this cannot be done. In the jaws A Athere will be a dovetailed seat or recess to receive and hold the dies13 B, the extremities of the seat or recess of each jaw being inclinedor beveled in opposite directions to form the dovetailed seat, in whichis fitted the removable die, which is beveled at its ends to adapt it tofit tightly therein. The dies B B will be held in place by keys or othersuitable means, substantially as indicated in Fig. 1. The (lies B 13 areto have numerous and sharp corrugations, hardened, so as to be capableof reducing or shaping the desired metallic article. This is done byplacing the article to be shaped lengthwise between the jaws of thetool, closing the jaws tightly down 011 the same, and then, by means ofthe handles 1) Z) the work of reducing begins. This work is continuedtill the ends of the jaws come together, when it can proceed no furtherwith out changing tools or making achange in the size of the dies.

In size the dies B B will be various in length as well as in thickness.Although it is necessary for the corrugated sides of the dies to beconcave, yet the reverse side need not necessarily be convex, for a flatsurface will do as well by forming the jaws A A to conform thereto.

A tool formed as described and shown will be of great utility in shapingor working in places where a lathe cannot be had or where one could notbe used. It will be comparatively small, so that it can be easilycarried about, and hence much time will be saved and expense also.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 15-" 1. A metal-working tool of the class described,consisting, essentially, of two segmental jaws formed integral withpivoted handles, and segmental dies fixed to the opposing edges of saidjaws and having the serrated workingfaces, substantially as and for thepurpose described.

2. A metal-working tool for reducing oblong or other shaped metallicarticles to an approximately-cylindrical shape, consisting, essentially,of a pair of segmental jaws formed integral with handles which arepivoted together, and the segmental (lies conforming to the curvature ofsaid jaws and removably fixed to the inner opposing edges of the jaws,said dies having the serrated Working-faces, substantially as and forthe purpose set forth.

A metal-workil'lg tool of the class described, consisting,essentially, of two segmental jaws which are made dovetailed in hereuntoaflix my signature this 8th day of cross-section, the pivoted handles,and the March, A.
